Governor Huey Pierce Long Jr actually the grandson of William Rochelle Horton per DNA.
Hello.
Is there any DNA proof that Governor & Senator Huey Pierce Long Jr is actually a grandson of William Rochelle Horton?
Thank you for any assistance.
Goodbye. — Preceding unsigned comment added by 184.98.61.88 (talk • contribs) 02:55, 26 July 2015
- I assume that you are referring to the Governor Huey Pierce Long Jr who was assassinated in 1935: if there is DNA evidence, there doesn't seem to be anything that Google finds to show it. If you are referring to this William Rochelle Horton [1] (the dates seem about right), it might theoretically be possible to compare DNA of living descendants (assuming there are any) but I think they might want to know why the relationship was being claimed - where did the suggestion come from?

Battery Back-up on traffic signals
Can Battery-Backup be done on traffic lights if there is incandescent on any of yellow lamp. Because when I went to meet the traffic engineers at Mission Viejo the guy said to have battery backup all three colors will have the LEDs, the way it works is for the first two hours the traffic light will still go through red, green, yellow phase cycle, then the next two hours green lights stop working, what I will see is red lights will flash, after that is full black outs. When I called City of Irvine on the phone the guy told me battery backup can be done if yellow lamps are still incadescents, it is just better when all red, yellow, green is LEDs. I have seen it happen alot when green lights stop working and red lights flash, when that case scenario does it have to do with Battery Backup. I remember ten years ago in my Metropolitan Area there wasn't even LEDs on the Yellow lamps, the LED for most of South Orange County Area were only Red and Green since they were considerably more frequently illuminated than the Yellow ones, because I remember at that time I saw Red lights flash and Green lights stop working I was wondering if it has to do with Battery-Backup.--107.202.105.233 (talk) 04:12, 26 July 2015 (UTC)
Green lights stay on when there is no vehicle in demand
I thought is weird when Green lights stay on when there is no traffic in demand, because I know the rule is when there is no traffic movement in demand, the green signal demands suppose to skip completely, but sometimes during weekday rush-hours I have seen that case when green light turns on even when there is no traffic movement in demand. Could this be programming error, when the data is not reading information properly or the computer programming are done on purpose and there is a reason why the traffic engineer done it that way. And also since I tend to obsess traffic lights and want to know all the details as possible, if I want to know left turn vs. straight turns, which corners (side A or B) are more likely to skip the green signal demand, is it better to watch the signals when traffic are greater (Weekday during high volume traffic), or is it a better idea to do it when the traffic volumes are lighter (Like on Weekends or early morning or later at night), because as I noticed when left turn pockets have smaller cars, what happens is the green signals timing are shorter on side A and green signals timing are longer on B. Because sometimes I tend to do it and ignore the fact I may not get the accurate readings I hoped when during that time green lights just goes through full demand phasings.--107.202.105.233 (talk) 04:21, 26 July 2015 (UTC)
- Assuming these are questions about the US, when there is no signal it is normally dealt with as if there were a red signal. You'll want to look at the relevant state laws for your local jurisdiction. μηδείς (talk) 04:30, 26 July 2015 (UTC)
- (Your question is very hard to understand. Please repost in your native language, and we will translate it to English.)
- Most traffic lights are still timed, not using sensors to detect when traffic is present, at least where I live. And even where they do use sensors, in the absence of any input from the sensors they might still go back to timing, in case the sensors are broken. StuRat (talk) 04:27, 26 July 2015 (UTC)
- I am asking about battery backup does all of the colors have to be LEDs, or you can do it a battery back when the Yellow lights is incadescent or all three colors are incadescents, because I have seen it when red lights flash and the green lights shuts down. I know on that intersection the Yellow light are incadescent, I have seen it when red lights flash and green lights stops working, and all red, yellow and green lamps are incadescent, does the red lights flash and green lights stop have anything to do with battery backup, or there is some other reasons like there is something wrong with the lights traffic engineers have to go through the system and fix it. (Oops I talked too fast on the battery backup part, I do have trouble controlling myself when I discuss traffic lights topic)--107.202.105.233 (talk) 04:38, 26 July 2015 (UTC)
- (You really need to read and fix your posts, to make them clearer, before submitting.)
- I always assumed the reason why traffic lights go to flashing red and yellow during a power outage was that they become unable to coordinate the timing with adjacent intersections, and it's safer to slow people down with flashing yellow and red lights than to have them continue as if nothing was wrong, even though the traffic patterns will be all messed up. A related thought is that if they get the timing signal from AC current, and lose that when they go on DC backup current, then they may have to rely on less accurate timing methods, again making coordination of timing with adjacent intersections impossible. (I've noticed that my clock radio keeps abysmal time when on the battery backup.) Another twist might be if regulations regarding how the lights behave were made when different technology was used, and the rules have never been changed. StuRat (talk) 04:44, 26 July 2015 (UTC)
- In NJ at least, there are two reasons. Flashing red and yellow is common at rural intersections where most of the traffic is along the route with the yellow light, which need only be cautious and not stop. Flashing red and yellow seems also to be the default with outages, which would match with the speculation above. I have never seen this in NYC, and most roads in Jersey that would really need a four way stop have four stop signs or a cloverleaf (traffic) or a traffic circle. For a permanent red/yellow, see the intersection of Mathistown Road and US Route 9 {just north of Penny Lane) in Little Egg Harbor Township, NJ. μηδείς (talk) 21:37, 27 July 2015 (UTC)
- My uncle lives in Little Egg Harbor. :-) StuRat (talk) 22:35, 27 July 2015 (UTC)
- It's a very nice area, my parents had a house on Great Bay, which they sold, luckily, a few months before Sandy. My dad keeps a boat in Tuckerton. An update on the light at Rte 9: it has been changed to a normal timed light. Used to the light remaining red, he ran it, not realizing he had to wait for the green until after he made the left on red. μηδείς (talk) 17:43, 28 July 2015 (UTC)
Three Newport Mansions
I'm trying to confirm the identity of three of the mansions along lower Bellevue Ave. in Newport, Rhode Island.
- 570 Bellevue Ave, at 41°27′48″N 71°18′18″W / 41.4634°N 71.3051°W. According to this article, this is the address of Beechwood. Vast construction activity can be seen in the current Google Earth / Google Maps imagery, tending to confirm this hypothesis.
- 614-618 (approx.) Bellevue Ave., at 41°27′39″N 71°18′16″W / 41.4609°N 71.3045°W. According to Wikipedia, this is Beechwood, although I'm inclined to doubt it. This map (from the Cliff Walk website) suggests it might be Clarendon Court.
- 624 (approx.) Bellevue Ave, at 41°27′35″N 71°18′20″W / 41.4598°N 71.3056°W. This article suggests that this is Clarendon Court. I'm not sure how reliable this article is; I wouldn't normally look to Variety as a font of architectural or georeferential knowledge, although the article does happen to include some floor plans which are clearly much closer to the building at 624 than either of the ones at 614-618. We don't have an article on Clarendon Court, although of course it's mentioned in our articles on Claus and Sunny von Bülow.
I've also got a query open at Talk:Beechwood (Astor mansion). I've very close to changing the coordinates on our Beechwood (Astor mansion) article to match the 570 Bellevue address, but I'd like to double check by confirming what's actually at the 614-618 address if not Beechwood.
If anyone happens to be in Newport, there's a historical marker across the street from Marble House that would probably resolve this. (I was there yesterday, but it wasn't until I got back that I discovered this mystery, and I didn't think to take notes.) —Steve Summit (talk) 23:29, 26 July 2015 (UTC)
- Never mind on most of that; someone at Talk:Beechwood (Astor mansion) has answered already. Steve Summit (talk) 23:48, 26 July 2015 (UTC)Resolved

What is this heroic trope?
Guys what is this heroic trope? Let's say Bob is our hero and wants to kill King Charlie who rules as a tyrant in the Kingdom of Alice. Bob wants to kill Charlie for revenge and doesn't care about what happens to the Kingdom. Still, the kingdom is saved when he finished his task. The citizens of Alice wants to congratulate him but Bob simply moves on. Thanks in advance. --Lenticel (talk) 01:37, 27 July 2015 (UTC) --Lenticel (talk) 01:37, 27 July 2015 (UTC)

Notable people dying at Hiroshima and/or Nagasaki
I am very surprised that not even one notable person was among those killed by the atomic bomb. I mean, didn′t these cities have mayors or governors? If someone dropped an atomic bomb today on Somerville, which has now less population than Hiroshima did in 1945, certainly there would be many people with Wikipedia articles among the dead. Maybe we have missed some from Hiroshima? 2A02:582:C55:2A00:E58C:3FFC:F108:2131 (talk) 14:29, 27 July 2015 (UTC)
- Category:Hibakusha may help. It includes survivors as well as non-survivors. -- Jack of Oz [pleasantries] 20:11, 27 July 2015 (UTC)
- I would assume that a large fraction of the problem here boils down to two things:
- Since the city was mostly reduced to ashes, many of the records that would enable us to establish notability may well have been annihilated.
- English Wikipedia is dependent on it's contributing authors to write about such things. Only a very small percentage of us speak and read Japanese well enough to find and understand the source material, and only a tiny fraction of that faction will be interested in writing biographies and an even smaller fraction of that fraction will be interested in people from that time and place. So the pool of people who are working on such matters is likely to be exceedingly small.
- Because of the way Wikipedia is written, it's inevitable that our coverage will be patchy, suffering from "recentism" and a bias towards articles about people from English-speaking countries. Please don't interpret this as people being biassed one way or the other - it's just in the nature of a set of disorganized volunteer contributors.

- Ronald Shaw is one notable, a British prisoner of war in Nagasaki. Adam Bishop (talk) 12:19, 28 July 2015 (UTC)

- Yes, yet another yankee friendly fire event. I wish your guys would f**king choose their targets carefully. KägeTorä - (影虎) (もしもし!) 01:37, 29 July 2015 (UTC)
- From the British POV the dropping of the bombs ended the war early, saving millions of lives, including thousands of British prisoners in Japanese POW camps that were closer to death camps. So, that was well worth the price of one British death.
- I understand that Japan is now trying to change their Constitution to allow fighting abroad by their military. If this happens, they will find out it's rarely possible to kill only the enemy without any innocents being harmed. The only alternative left is to leave ISIL, etc., unchallenged to grow and commit genocide. StuRat (talk) 14:29, 29 July 2015 (UTC)

Favoured drinks in the American Old West
Comics such as Lucky Luke and Punaniska have shown that men in the American Old West generally drunk whisky in saloons in the west. I imagine they may also have drunk beer. In fact, one Punaniska comic shows Calamity Jane offering Punaniska some wine, which he immediately refuses, thinking it would challenge his masculinity. What was the situation in real life? Did they really almost always drink whisky? And what sort of whisky? American instead of Scottish or Irish, I should presume? Did they have any preferences or did they just want to get drunk quickly? Did they also drink beer and wine? What about non-alcoholic beverages? JIP | Talk 20:35, 28 July 2015 (UTC)
- Absinthe might be included in the list of alcoholic drinks, until banned in the US by 1915.
- As for non-alcoholic beverages, there were many variations on root beer, such as ginger ale and sarsparilla. Note that while Coca-Cola has roots going back to the 19th century, it was sold as a patent medicine then, in drug stores, not saloons, as it contained cocaine. StuRat (talk) 21:01, 28 July 2015 (UTC)
- Moonshine and Corn_whiskey. Note the former has a name from England but took on its own prominence in America, while the latter, strictly speaking, is a product of the New World. Here are two relevant books I found on Google that would almost certainly give you better info and more context [2] [3]. SemanticMantis (talk) 13:42, 29 July 2015 (UTC)
- Bourbon whiskey was the preferred drink because (a) it was relatively cheap, being made mainly from corn (maize), the most widely grown crop in America, and (b) it was easy to store and transport. In the old west the ingredients were not available to brew beer locally, and it didn't keep well enough to be transported by railroad at reasonable expense. Wine was easier to store and transport than beer, but it was still a luxury item. It wasn't just the old west by the way -- even in the east Bourbon was by far the most commonly consumed form of alcohol. Looie496 (talk) 13:53, 29 July 2015 (UTC)
- Hm. As for east of the Mississippi, recall Johnny Appleseed gave the gift of booze to the (then) western frontier - his nurseries and orchards did not make tasty apples, they were used for hard cider and applejack, which were both very popular as well - very easy to make in large swathes of the country, less so west of the Mississippi at that time. I'm not saying that apple booze was more popular than Bourbon necessarily, just that it was much easier to make at home than beer, and required less special processing.

- A webpage called Saloons of the American West mentions "Cactus Wine, made from a mix of tequila and peyote tea, and Mule Skinner, made with whiskey and blackberry liquor. The house rotgut was often 100 proof, though it was sometimes cut by the barkeep with turpentine, ammonia, gun powder or cayenne" but says that the main drink was rye whiskey or bourbon, also beer served at room temperature.

Chance of being born?
So, at one stage you consisted of spermatozoa in your dads testicles. I read that a mans testicles make 1000 sperm a second. So that's 60,000 sperm a minute. I'll let you do the math, but on a particular day your parents decided to have sex and fertilised your mommas egg.
Have I got the premise wrong or what, but did you I and everyone else have an astronomically minute chance of even existing in the first place. I mean, if another sperm got inside the egg or you didn't survive the ride through your dads epidermis and into your moms vagina you wouldn't have existed? Would the baby born be a difference person altogether. Or are are all sperm the same.

- You can ignore biology and instead read up on interpretations of probability, and the ontology of identity, both in terms of personal identity and identity_(philosophy). When people have sex, we can come up with an estimate of chances of pregnancy. When a woman gets pregnant, we can relatively easily look at some statistics and come up with an estimate of percent chance of live birth. But none of that rationale applies to the chances of me being me, or you being you (and we need to acknowledge that this concept is ill defined). Colin and TPFKA's links are good and relevant to the bits of biology, and you should also be aware of nature vs. nurture and twin studies and heritability. But I think this is really a question about philosophy of probability and identity :) SemanticMantis (talk) 13:36, 29 July 2015 (UTC)
- The probability of "you" being precisely, genetically "you" if anything whatever were different at the time of your conception is indeed astronomically small. However, not all of what makes you be "you" is in your genes. A lot of it is how your parents treated you, what foods you ate, what diseases you got - that kind of thing. If a different sperm had made it into your egg, a lot of that "nurture" stuff would be very similar. So, it would be as if you were your own twin (but not identical-twin). Twins that are non-identical are very often quite similar.
- But in terms if being identically you - everything depends on how identical you're talking about.
- If the same sperm met the same egg - but three days into pregnancy, if your mother had eaten something different than she actually did - then that would undoubtedly change some microscopic detail in that tiny ball of cells - and an entirely different "you" would emerge from that process. Genetically identical to the you that we know - but still more different than one of a pair of identical twins. (My step-daughters are identical twins - and I can tell you that they are far from identical in many significant ways).
- Conclusion: The "you" that would emerge if there were a difference in some small detail surrounding your conception, pregnancy, birth and early childhood would range from roughly what a fraternal twin would be like - to roughly what an identical twin would be like - depending on whether the change happened before or after sperm-met-egg.
- SteveBaker (talk) 14:10, 29 July 2015 (UTC)
- I'd point out that a mere difference in a meal is unlikely to have an effect on a fetus unless it contains a teratogenic toxin. The fetus will thrive so long as threshold levels of the necessary nutrients are available, and certain toxins are avoided or minimized. The sort of change that could effect a baby during development is a somatic mutation. Such a mutation at a very early stage in one of two twins might have noticeable effects. Otherwise twins are sometimes differentiated by position in the womb, especially the relative size and bloodflow from the respective or shared placentas.
- The overall concept here is historical contingency. There are certain focal points such as which numbers you choose and which numbers are drawn in a lottery. The path you take to get to the store to buy the ticket might not matter at all, if you have already made up your mind on the numbers you want beforehand. In his book Wonderful Life, S J Gould examines contingency in depth. He gives the case of a single dog that is believed to have killed a significant portion of the wild Kiwis of New Zealand. Had it not been stopped, it might have driven the species extinct.
- Another example is my neighbor, who did not work at the World Trade Center, but who was at a conference there on the Windows of the World restaurant, and was killed on 9/11. Certain events are canalized, and others are tipping points. μηδείς (talk) 20:54, 29 July 2015 (UTC)
- I thought this nonsense had been zapped. Be that as it may, the OP's premise is wrong. You don't start out as a sperm, you start out as a fertilized egg. ←Baseball Bugs What's up, Doc? carrots→ 22:21, 29 July 2015 (UTC)
- The definition of "you" is kinda fuzzy. All of the information needed to describe "you" (genetically speaking) is present before sperm meets egg - so who is to say when "you" are "you"? One of the severe problems with the abortion debate is in answering this very question - contraception for the catholic church revolves around similar issues. Personally, I liked Monty Python's "Every Sperm is Useful" song - which encapsulates a yet further extreme point of view. Coming up with a specific point of origin is horribly misleading. I'm a very different person than I was (say) 10 years ago - was I "me" then? I just don't think you can pick a single point and call that "The Moment". SteveBaker (talk) 23:29, 29 July 2015 (UTC)

- The definition, Steve, isn't really fuzzy. Instead, you are you is axiomatic. By definition you have to be you, because if you weren't you, then the you you really were would be you, and I'd be writing in response to someone else. It's like the anthropic principle. It's not really a physical explanation of anything, but it is necessarily true epistemologically as a precursor of debate. μηδείς (talk) 00:00, 30 July 2015 (UTC)
- The term, from formal logic, is Tautology, which in the non-pejorative sense, just means "universally true under all conditions"; a classic example is the Law of identity or the famous Aristotlean proposition A is A. That is, we must always assume that a thing is always itself, for any given complete definition of the thing. The idea that "you are always you" is a logical tautology; for the reasons noted (if you weren't you, you'd be a different person, but that different person would still be you, and you wouldn't then have been the person you are now, so that you wouldn't be you anymore. Or, you are always you). Besides that particular tautology, is the definition of The Universe which, under it's simple definition of "everything", means that one cannot have more than one universe, merely only that one can learn more about what is in The Universe. Other classic logic or philosophy problems are based on tautologies, some with long histories, such as the primum movens argument for God, or the philosophy behind the atomists like Democritus. --Jayron32 19:22, 30 July 2015 (UTC)

- The definition of "you" is kinda fuzzy. All of the information needed to describe "you" (genetically speaking) is present before sperm meets egg - so who is to say when "you" are "you"? One of the severe problems with the abortion debate is in answering this very question - contraception for the catholic church revolves around similar issues. Personally, I liked Monty Python's "Every Sperm is Useful" song - which encapsulates a yet further extreme point of view. Coming up with a specific point of origin is horribly misleading. I'm a very different person than I was (say) 10 years ago - was I "me" then? I just don't think you can pick a single point and call that "The Moment". SteveBaker (talk) 23:29, 29 July 2015 (UTC)
Today's Feature Picture
Today's feature picture of NGC 1097 shows it rotating clockwise, the picture in the posted link to NGC 1097 shows it rotating counter clockwise. Which is correct?70.30.7.110 (talk) 14:38, 29 July 2015 (UTC)
- For convenience, NGC 1097. I think OP is comparing the top image to the bottom image.
- I think it's safe to say that the images were not take from different sides of the galaxy :) I cannot tell which one is a mirror image. I don't think it can be the case that they are showing different structures in the same galaxy from the same perspective without reflection - but I don't know much about spiral galaxies. Both images are sourced - top one is a composite image here [4] Spitzer Space Telescope, bottom one (seems to be a single image?) here [5], from the Very Large Telescope. SemanticMantis (talk) 15:44, 29 July 2015 (UTC)
- I downloaded them both, and rotated and flipped one of them so that their orientation is similar. The patterns of various points of light seem to match. So one of the images was flipped, either purposely or by the type of telescope they were using. ←Baseball Bugs What's up, Doc? carrots→ 17:22, 29 July 2015 (UTC)
- This sort of flipping of images is quite common in old-style print media dealing with physical plates that can be reversed accidentally during layout or printing. Unless there's written words in the image it is often impossible to know which is right. This seems less likely in digital media, however. μηδείς (talk) 17:33, 29 July 2015 (UTC)
- If you do a Google Images search on "NGC 1097" - you get a surprising mixture of clockwise and anticlockwise images. I'd say that the preponderance of them is per the top image - but it's definitely not a slam-dunk one way or the other. Most JPEG files have orientation data stored in an "EXIF" record - which should (in theory) tell you when they are rotated or flipped and in which direction. However, when people use a program to crop, recolor or adjust contrast on the image, that data is easily destroyed...so it's still not conclusive evidence. SteveBaker (talk) 19:34, 29 July 2015 (UTC)
- The EXIF orientation value indicates the raster order of the encoded pixels, not the orientation of the image relative to some canonical source image. Almost all software writes JPEG images in the standard raster order (English reading order) with a matching (or omitted) orientation tag, because that's the most compatible format. This doesn't destroy any (relevant) information because the raster order is a low level encoding detail, like the Huffman tables. As far as I know, no software ever writes the reflected raster orders (2, 4, 5, 7). -- BenRG (talk) 23:27, 29 July 2015 (UTC)
- Indeed. But many software packages don't pay attention to the EXIF data, resulting in these kinds of issues. I know of at least a couple of cellphone camera apps that use the reflection flag when using the 'front camera' in order that the user gets a mirror-imaged photo when taking a 'selfie' (which is what they seem to expect will happen). It's plausible that astronomy packages might use it to flip pictures from telescopes that naturally produce inverted images. That would be a fairly plausible explanation as to how this came about...but it's just speculation at this point since there are no unusual EXIF flags in either of those two JPEG files and there are many software packages that might have been used to crop the images that both ignore and destroy the EXIF information. (The EXIF flags aren't a part of the core JPEG specification anyway - so there is some justification for doing that.) SteveBaker (talk) 14:53, 30 July 2015 (UTC)

- Can we figure out which is correct by the LEDA entry?—eric 00:21, 30 July 2015 (UTC)
- I spent an embarrassing amount of time trying to figure this out with no luck.. I am really curious and hope that someone comes along with the right answer. I did learn that some galaxies have a spin different than what you would think and based on this alone I'd put my money on the bottom image and that the top one was flipped because of the type of telescope or imaging instruments, but that's just an unsubstantiated guess. Maybe someone could repost this to the science section?? Void burn (talk) 05:43, 30 July 2015 (UTC)
- If OP or anyone else wants to cut to the chase, they could ask NASA here [6], though it may take them a few weeks to get back to you. Could probably even point them to this thread for context. SemanticMantis (talk) 20:07, 30 July 2015 (UTC)

Article About Resona Holdings
The picture in the article https://en.wikipedia.org/wiki/Resona_Holdings#Group_companies shows three pictures of which the upper one is not associated with Resona. The picture called "Resona Holdings headquarters in Koto, Tokyo, Japan" is not Resona's location. Resona is located in a nearby Building few meters away. You may check this on Resona's homepage: http://www.resona-gr.co.jp/holdings/english/about/outline/office.html

Requests for past medical records
I am currently on Klonopin and Adderall and have been for 2 years. I recently moved and have had to see a new psychiatric provider. This new psychiatrist is demanding that I sign a release of information for him to speak with, and obtain records from, my previous provider if he is to continue prescribing those medications, but otherwise does not object to prescribing them. I do not want to release these records, and I am wondering if this is typical (for a psychiatrist to refuse to prescribe medications without speaking with and reviewing the records of the previous provider). — Preceding unsigned comment added by 169.244.19.161 (talk) 20:16, 30 July 2015 (UTC)
- I would think any doctor would want to see a given patient's history on any medical matter. As to whether he can compel you to do so, that's a legal question and we can't answer it, first because we're not allowed to, and second because any laws relating to this subject could be specific to your region. ←Baseball Bugs What's up, Doc? carrots→ 20:55, 30 July 2015 (UTC)
- Since medical professionals don't (or aren't supposed to) prescribe medication to anyone who walks in an asks for it (especially substances with a high potential for abuse like Adderall), in order to prescribe without going through typical diagnostic processes, they would need verification from whoever performed the diagnosis and determined these two medicines are most appropriate. After all, there's no way for them to tell someone like yourself who has been taking medication and simply wants to continue it from someone malingering or otherwise being dishonest. Laws about medical privacy vary depending on where you are. If you're in the US, take a look through the Department of Health and Human Services page about sharing information related to mental health. — Rhododendrites talk \\ 23:02, 30 July 2015 (UTC)

Urinating / defecating simultaneously?
Are humans the only species that can accomplish the same task at once? Obviously, I only speak for myself here but I've never witnesses any other common animal do the same thing, save for birds. — Preceding unsigned comment added by 42.114.5.58 (talk) 08:33, 31 July 2015 (UTC)

- And birds and reptiles, who do not have separate exits in their lower abdomens, but rather have a single orifice called a cloaca which is used for all reproductive and excretory function. See Bird anatomy#Kidney which describes who urine moves from the kidneys to the cloaca, but rather then be excreted directly, migrates back into the colon where it mixes with bird feces before being eliminated together with them. --Jayron32 16:58, 31 July 2015 (UTC)
Double Digestion in humans
Does double digestion ever occur in humans? It seems odd that most of our primate relatives practise it and we do not. In fact, a lot of food seems to quite literally go down the toilet merely because it never had a chance to get absorbed the first time round. (Onions, sweet corn, seeds) Or, did humans naturally engage in behaviour and it simply being a case of modern culture deeming it inappropriate. — Preceding unsigned comment added by 76.106.33.151 (talk) 16:55, 31 July 2015 (UTC)
- Humans don't do this because their digestive system is extremely efficient (although yours seems a bit sub-standard). Animals that do this generally have poor digestive systems and/or have a primary food source that is difficult to digest, such as rabbits and grass. Which primates do you think eat their own faeces?--Ykraps (talk) 17:42, 31 July 2015 (UTC)

- Okay, but given that those are our two closest relatives, it's reasonable to ask about why humans generally don't do it. I suspect that our guts aren't particularly more efficient than a chimp's (though, if so, that would serve as at least a provisional explanation). 64.235.97.146 (talk) 18:30, 31 July 2015 (UTC)
